I have an Ntech. Very pleased with it, a noticeable difference on the butt dyno over stock cat, a lot quieter and less smelly than going just with mp.

I have a Gotham Racing hi flow and love it. It allowed me to pass emmissions and go to 12 PSI with DP, catback, Intake, IC and ECU upgrades.

Do you have a need for one immediately? If not, I would wait to see what happens with these newer technology cats. Having almost the same flow as a midpipe but being able to retain emissions will be fantastic if they live up to their hype.

Pretty much all of the hi-flo's currently available will give you a noticeable increase over the stock cat, as well as being MUCH lighter.

no i am not in need of one right now, your i think i am going to wait , but if they are not as good as it seems, i just want to know whats next best out there..

Right now, the 2 most "proven" hi-flo's are the Bonez and the N-Tech. Gotham just started selling their hi-flo so people haven't had them long enough to really give a longevity report.

Also, there are threads of people welding Megaflow (or some company like that) Hi-Flo cats into midpipes which seems to be another cheaper alternative. However, as with Gotham, nobody has had the setup long enough for longevity reports.....

right thats something i wanted to know also longativity... i dont want it clogging up in 1k or 2k miles like that pettit. ive seen a few of those welded ones too dont know the name myself. the reason i like the gotham the most is because of the "plug and play" with the airpump and all.

Unfortunately, you'll have to wait a while on a longevity report for the Gotham Hi-Flo (I think it's only been around less than a year).

The only other "plug & play" Hi-Flo out there (worth a damn) is the Bonez, but it's quite expensive. However, IMO, it was well worth the money (I'm using one).

i have the bonez. When i was searching for a HFcat awhile back, i decided to go with the bonez. All i heard was good news from people using that cat, and having the people @ rotary power in south cali also recommend it just sealed the deal

Also see, Resonated Midpipe (if you dont mind killing the earth)

i would get a midpipe but i cant stand that smell... i have to get some sort of cat.. right now i am waiting on the new metal cats.. but i am leaning towards bonez.. but i would also like to see how gotham racing becomes in the future.
